From: Two-photon interference of polarization-entangled photons in a Franson interferometer
Experimental results. (a) Measured HOM peak and dip fringes as a function of Δx 1 for degenerate photon pairs when Δx 0 = 0. (b) Coincidence probability as a function of Δx 2 for Δx 1 = 0. (c) Phase resolved fringe of (b) measured by varying Δx 3 for Δx 2 ≈ 0. (d) Polarization correlation measured as a function of P2 rotation angle, with P1 fixed at +45°.
